WIP: Bump ANSIBLE_VERSION_MAX to 2.14

[opoplawski]

Thanks for creating a PR! Here's a quick checklist to pay attention to:

• Please add an entry to docs/changelog.rst as appropriate.

• Has some new parameter been added or semantics modified somehow? Please ensure relevant documentation is updated in docs/ansible.rst and docs/api.rst.

• If it's for new functionality, is there at least a basic test in either tests/ or tests/ansible/ covering it?

• If it's for a new connection method, please try to stub out the implementation as in tests/data/stubs/, so that construction can be tested without having a working configuration.

Worked in my minimal testing - hopefully mitogen has some CI that will run...
